Completed level 9 last night. The end of the level with the spiral corridor layout was a proper 'rabbit in the headlights' moment. Turned the corner and there's a troll prepping to charge at me. SHIT! Then legging it back through the spiral corridors, hearing the troll stampeding behind me was easily the most terrifying moment in the game.

The second troll is especially nasty, due to part of the spiral corridor route being blocked and requiring a button to be pressed.
